The Lowdown
Hey, Rusty here. We’ve only got one break on the radar for this 16-day stretch, so let’s get into it for Costeño Beach.
We kick off on Friday, September 11th. The morning is a bit junky with a cross-onshore breeze messing up a 5ft NE swell. The wave energy is moderate (281). The afternoon turns glassy though, and that same 5ft swell cleans right up. That’s the sign of better things.
The best window is hands down Saturday, September 12th. Saturday morning is pure gold. A clean 7ft NE swell with dead glassy conditions. The combined energy is solid moderate (545). The wind is zero, the swell is smooth, and with the 8-second period, you'll be linking good turns. It’s beginner-friendly size, and the crowds are only *sometimes* there, so you can spread out. Saturday afternoon is just as good – 6ft NE and glassy (517 energy). This is the standout. Water temp is about average for the time of year, nothing crazy.
Sunday the 13th the swell backs off to 5ft-6ft, and the wind turns cross-on. It’s still rideable, but not as crisp. Monday morning the 14th turns glassy again with a 5ft NE swell – a decent, clean session.
Things get iffy from Tuesday the 15th to Wednesday the 16th. Tuesday offers poor surf with cross-winds, and Wednesday morning is nasty – choppy conditions on a 7ft swell with a short 7-second period. Don’t bother.
Wednesday afternoon the 16th flips back to glassy with a 6ft NE swell (352 energy) – surprise. That glassy vibe sticks around through Thursday the 17th with waist-to-chest high waves (4ft-5ft).
From Friday the 18th onward, the swell fades fast. Friday and Saturday still have small, glassy waves (4ft-4ft), but by Sunday the 20th we’re down to 3ft slop. That continues all the way to Saturday, September 26th. The energy drops way low (under 100 for most of it). Very weak, ordinary waves.
So, get your best session in on Saturday, September 12th. After that, pick the glassy mornings for a small wave cruise.
Rusty.

Information about the Costeño Beach Surf forecast
The above surf forecast table for Costeño Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Costeño Beach can be found by selecting the local surf guide option on the grey menu. Our Costeño Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Costeño Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Costeño Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
